GAS-HEATER.

Specification forming part of Letters Patent No. 103,297, dated May 24,1870.

To all whom it may concern:

Be it known that I, OALVINO. BURT, of the 'city and county of Jackson,and State of Michigan, have invented certain Improvements in theGenerating and Burning of Gas from Gaseous Fluids or other Substances,of which the following isa specification.

My invention relates to certain improvements inapparatus for generatingand burning gas or vapor from heated volatile fluids, such as form,whereby valves are dispensed with and a uniform supply produced;finally, in the general construction of the gas-heater, as hereinat'terdescribed. Figure l is a side elevation. Fig. 2 is aver- Fig. 3 is asimilar section of the hollow oxygenated burner detached.

Similarletters of referenceindicatelike parts in all the figures. v

A represents a portion of the vertical supplypipe, which, as in otherapparatus for the purpose, leadsfrom a tank or reservoir, and isprovided with a stop-cock, neither of which is shown, being Well-knownappliances.

B is the horizontal branch pipe, forming a part of the gas-generator. Itis screwed to the two elbows O 0, one of which connects with thesupply-pipe and the otherwith the burnerhead. I

D is the injecting-tube, which is placed inside thepipe B, as shown. Theopen end of the tube is enlarged and threaded to fitcorrespondingthreads formed in the bore of the pipe B at its end joining the elbow O,and the being laterally deflected, issues through the spaces andorifices m and a, the heat from the canopy-plate being conducted backthrough the sections S, which connect the canopy with the base carryingthe cone.

In the noiseless burner G, as shown at Fig. 3, the flame from thecone-orifice issues into a cup-shaped chamber, and the flame, strikingthe canopy E, (screwed on the cup,) is deflected through thejet-orifices e e, 850., around the periphery. An aperture, a, is madethrough each wall of the burner in range with and on a level with thejet-orifice, as shown by the line :0, to admit the common air to blendits oxygen with the carbureted hydrogen from the cone-orifice in such amanner as to produce a noiseless combustion entirely free from theslight detonations accompanying the burning of gas or vapor in an openburner similar to that shown in Fig. 1 This mode of producing silentcombustion, although attended by ta certain loss of caloric, isnevertheless useful for certain purposes where an intense heat is notdemanded, and to quiet the unnecessary The stop-cock being then opened,the fluid will pass down the supply-pipe A into the injecting-tube D,and from thence through the perforations into the generating-chamber,where it is converted into gas or vapor, which fills it and the annularspace a around the tube D and issues through the cone-orifice t', whereit is ignited. The lamp may now be withdrawn,

. as the necessary heat is perpetuated by transmission from theburner-canopy, as aforesaid. As the injecting-tube is surrounded by gas,

the contained fluid is protected from undue heat and kept solid andquiescent, in which state it is impermeable to the passage of the gas.

The usual mode of admitting the fluid to the generator is by. unscrewinga valve next the supply-pipe. This is a wasteful and defective plan,'forthe supply is usually in excess, and the fluid being unprotected at thepoint of issue, it becomes heated to ebullition, and the gas forcesitself through the globules, and, permeating the whole mass, escapesthrough the vent-hole of the tank into the room, emitting an offensivesmell.

By making the tube D tapering, as shown, valves are dispensed with, andthe supply of the fluid to the generator is uniform, and the shell ofthe injecting-tube being enveloped in the gas or vapor of the chamber,the contained fluid can never be heated to the boiling-point.

I do not claim the arrangement of the injecting-nozzle within a pipewhich communicates with the gas-chamber. Neither do I claim broadly acone and a cup-shaped compartment having a flat disk-canopy, incombination with a burner-head, nor air-openin gs arranged at or nearthe gas-discharging orifice leading from the gas-chamber; but

I claim as my invention- 1. The burner H, with openings at a, cone I,and disk E, as set forth, for the purposes specified.

2. The injecting-tube D, arranged as described, when made tapering,whereby valves are dispensed with and a uniform supply produced, as setforth.

3. A gas-heater composed of the pipes A B D, elbows O O, and a burner, Gor H, with cone I, disk E, and side openings, allconstructed,arranged,andoperatingsubstantially as described.
